Operator page

Subsystems

propulsion

3 Raptor vacuum engines for lunar descent/ascent; additional RCS thrusters; methane/liquid oxygen propellants; requires on-orbit propellant transfer from Starship tankers before trans-lunar injection.

life-support

Integrated ECLSS hardware in development; SpaceX building life support, environmental control, and cabin systems for crewed surface missions.

avionics

GNC milestones completed per NASA progress reviews; autonomous precision lunar landing capability required.

power

Band of solar panels around vehicle circumference; kW capacity not publicly specified.

comms

Docks with Orion in NRHO for crew transfer; PDA (petal docking adaptor) interface; later Artemis missions require docking with Gateway.
